GRAIN-TANK FOR WAGONS.

SPECIFICATION forming part of Letters Patent No. 684,611, dated October15, 1901.

Application filed July 29, 1901- To all whom it may concern:

Be itknown that I, REINHOLD B. MARSHKE, a citizen of the United States,residing at Chaffee, county of Cass, and State of North Dakota, haveinvented new and useful Improvements in Grain-Tanks for Wagons, of whichthe following is a specification.

My invention relates to improvements in wagon-bodies or so-calledgrain-tanks for hauling grain.

The object of my improvements is to provide a simple and durable form ofwagon-body which is so constructed that the boards when shrunken may bedrawn together and the grain thereby prevented from escaping thererom.

The construction of my invention is explained by reference to theaccompanying drawings, in which- Figure 1 represents a verticalcross-section through one side'of the body above the rear axle, theopposite side of the body being like that shown. Fig.2 is a plan view ofthe wagon-body from which it is supported.

Like parts are referred to by the same references in both views.

A represents the bottom of the tank, which is formed of matched or socalled tongueand-groove flooring, which is supported on the cross-piecesB, to which it is secured by nails 0 in the ordinary manner.

D represents the sides of the wagonbody, which are of the usual width,extending vertically above the bottom toabout the height of the rearwheel. Extending upwardly and toward the right and left from the sidepieces D are two upwardly-curving walls E, which are also formed ofnarrow pieces of matched or tongue-and-groove floorin g, which aresupported from below upon the curved metallic ribs F, located at eachend and at intervals between the ends of the wagon-body. The matchedboards E are secured in place upon the ribs or cross-pieces F bycorresponding ribs or cross-pieces G, located upon the upper surface ofsaid matched flooring E.

The upper end of the rib F is provided with a horizontal bend H, whichengages over the upper edge of the series of boards E, while the lowerend of said rib F is provided with a nut I, operating on thescrew-threaded end J Serial No. 70,044. (No modeLE of said rib, wherebyit is obvious by turning down the nutI on said thread the several partscomprising the series of boards E will be drawn firmly together and thepossibility of grain escaping between the joints is avoided. The ribs Fand G are secured together by the series of bolts K, and the'aperturesin the ribs F and G, through which said bolts are inserted,are made slightly larger than the bolts or preferably slightlyelongated, so as to permit them to move with the series of boards E asthey are drawn together.

The lower edges of the side boards D are provided with tongues L, whichfit'in corresponding grooves M, formed in the upper surface of thebottom boards A, whereby grain is prevented from escaping beneath theedges of the side boards, as might otherwise be the case when the bottomboards become sprung with the weight of the load.

Located at intervals between the ends of the body'are a series ofmetallic strengthening-bars N, which are bolted to the sides D of thebody. The upper ends of said bars N are provided with angular bonds 0,which eugage the upper surfaces of the ribs G, while the lower ends ofsaid strengthening-bars N are provided with screw threads P and nuts R,whereby as said nuts are turned down on the threads P the said severalparts, including the cross-piece 13, bottom A, side pieces D, and thecurved portion of the body, are drawn firmly together. A series ofstrengthening-braces S are also provided between the curved pieces B andthe ribs F, which serve to support the upper curved portion of the body,as indicated in Fig. l.

T T are vertical end boards of the body, which extend across the bodyfrom one side to the other and are rigidly secured to the same at theirrespective ends, as indicated in Fig. 2.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A grain-tank for wagons, comprising a horizontal bottom formed ofseries of matched boards, interlocked together by tongues andgrooves-,and secured to trausversely-arranged cross-pieces; two verticalside pieces, the lower edges of which are connected. by atongtie-and-groove joint With the upper surface of said bottom pieces;two outwardlycurved side pieces formed of series of narrow boardsinterlocked together at their edges by tongues and grooves; series ofcircular ribs, supported at their lower ends from the upper edges ofsaid vertical side pieces, provided at their upper ends with angularbends adapted to engage on the upper edges of said interlocking boards,and provided at their lower edges with screw-threaded ends andclamping-nuts; an inner series of ribs, arranged parallel to said outerseries; and series of transversely-arranged bolts connecting said innerand outer ribs together.

2. A grain-tank for wagons, comprising a horizontal bottom formed ofseries of matched boards, interlocked together by tongues andgrooves,and secured to transversely-arranged cross-pieces; two verticalside pieces, the lower edges of which are connected by atongue-and-groove joint with the upper surface of said bottom pieces;two outwardlycurved side pieces formed of scriesof narrow boards,interlocked together at their edges by tongues and grooves; series ofcircular ribs, supported at their lower ends from the upper edges ofsaid vertical side pieces, provided at their upper ends with angularbends adapted to engage on the upper edges of said interlocking boards,and provided at their lower edges with screw-threaded ends andclamping-nuts; an inner series of ribs, arranged parallel to said outerseries; aseries of transversely-arranged bolts connecting said inner andouter ribs together; and series of strengthening-braces, supported attheir lowcrends from the bottom-supporting curved pieces, and connectedat their upper ends with said outwardly-curved side pieces.

3. A grain-tank for wagons, comprising a horizontal bottom,formed ofseries of matched boards A, interlocked together by tongues and grooves;transversely-arranged curved pieces B; two vertical side pieces I), thelower edges of 'which are connected, by tongue L and groove M, with theupper surfaces of said bottom pieces; two outwardlycurved side piecesformed of series of narrow boards E, interlocked together at their edgesby tongues and grooves; series of transversely-arranged curved ribs F,supported at their lower ends from the upper edges of said sides D, andprovided at their upper ends with angular bends H, adapted to engageover the upper edges of said interlocking boards, and at their lowerends with nuts I and screws J; an inner series of ribs G, said inner andouter series of ribs being connected together by transversely-arrangedbolts K; vertical strengthening-bars N, provided at their upper endswith angular bends O, and at their lower ends with clamping-nuts R,operating on screw-threaded bearings I; end-boards 1, extendingtransversely from one side of the wagon to the other; and brace-rods Scommunicating from the crosspieces of the bottom to said curved sidepieces, all substantially as and for the purpose specilied.

In testimony whereof I afliX my signature in the presence of twowitnesses.
